What is datefixR?

The messy-date parser rewrote its core in Rust and came out 300x faster.

datefixR standardizes inconsistently formatted dates — the kind that arrive from spreadsheets and hand-entered clinical or survey data, with mixed separators, ambiguous orders, missing components, and month names in whatever language the source used. Version 2.0.0 rewrote the parsing core in Rust, reporting over 300x throughput against previous versions through fastpath handling of common formats and parallel column processing via a cores argument. Version 2.0.1 then spent itself cleaning up after that rewrite, restoring ordinal indicator support, stopping malformed dates from being silently cast to NA, and reinstating error messages that had gone missing.

What is textshaping?

Rewrote its shaping engine for bidirectional text, then spent a year fixing what that broke.

textshaping is the text layout layer beneath R's modern graphics stack, feeding ragg, ggplot2 and marquee. Version 1.0.0 rewrote the shaping engine to honour the global direction of text, adding a direction argument that defaults to automatic detection, align settings that resolve against that direction, and ICU-based soft break locations that handle ideographic scripts properly. The five releases since have been consecutive bug fixes against that rewrite — bidi embedding arrangement, line positioning with mixed sizes, a weak hash in the shape cache, a signed integer overflow, and font fallback regressions.

The messy-date parser rewrote its core in Rust and came out 300x faster.

◆ Current state

datefixR standardizes inconsistently formatted dates — the kind that arrive from spreadsheets and hand-entered clinical or survey data, with mixed separators, ambiguous orders, missing components, and month names in whatever language the source used. Version 2.0.0 rewrote the parsing core in Rust, reporting over 300x throughput against previous versions through fastpath handling of common formats and parallel column processing via a cores argument. Version 2.0.1 then spent itself cleaning up after that rewrite, restoring ordinal indicator support, stopping malformed dates from being silently cast to NA, and reinstating error messages that had gone missing.

◆ Where it's heading

Two long arcs meet here. The first is localization: Russian, Indonesian, German, Spanish month abbreviations, and experimental Roman numeral months accumulated release by release, with full translation of user-facing messages treated as a goal rather than a bonus. The second is the migration off R for the parsing hot path — internals began moving to C++ around 1.3.1 before the Rust rewrite replaced that work entirely. The 2.0.1 regressions show the cost of that move, since behavior that was implicit in the R implementation had to be re-specified.

◆ Prediction

The Rust core is one release into stabilization and 2.0.1 was entirely regression repair, so expect further correctness fixes against pre-2.0.0 behavior before any new format support lands.

Rewrote its shaping engine for bidirectional text, then spent a year fixing what that broke.

◆ Current state

textshaping is the text layout layer beneath R's modern graphics stack, feeding ragg, ggplot2 and marquee. Version 1.0.0 rewrote the shaping engine to honour the global direction of text, adding a direction argument that defaults to automatic detection, align settings that resolve against that direction, and ICU-based soft break locations that handle ideographic scripts properly. The five releases since have been consecutive bug fixes against that rewrite — bidi embedding arrangement, line positioning with mixed sizes, a weak hash in the shape cache, a signed integer overflow, and font fallback regressions.

◆ Where it's heading

The package has moved from Latin-first layout to script-agnostic layout in two rewrites, 0.4.0 and 1.0.0, and is now in the long correctness tail that follows. The bug reports arriving from ggplot2, ragg and marquee issue numbers show how it works in practice: textshaping bugs surface as rendering defects in the packages above it, which is why so many fixes here cite another package's issue tracker.

◆ Prediction

Expect continued fixes driven by downstream rendering reports rather than new layout features, as the 1.0.x series stabilises. The font fallback path has produced two of the recent bugs and is the most likely source of the next.
